Study On The Exercise Intervention Of Lower Crossed Syndrome

Research purpose: The purpose in this study is to systematically clarify the possible mechanism of the Lower Crossed Syndrome(LCS),to reveal the rehabilitation effect of exercise therapy on LCS,and provide scientific theoretical basis for enriching and improving the formulation of LCS by comparing different intervention means.From the perspective of the whole human body,and the fascia chain is used as the entry point to provide an empirical basis for the formulation of exercise intervention prescriptions for the LCS.Research Method: 1.A survey of the influence of routine physical exercise on Lower Crossed Syndrome(Experiment 1)In order to know whether the effect of regular exercise on the LSC,69 patients were investigated,including 30 subjects study in PE,39 subjects in non-Physical Education College(NON-PE).All subjects were tested for spinal function,and take a picture of body posture evaluation.Subjects were collected including Thoracic Spine(TS),Lumbar Spine(LS)and Sac/hip J.,Incle.,Th1 to S3 back length,Anterior Pelvic Tilt(APT)data.2.Study on the exercise intervention of Lower Crossed Syndrome(Experiment 2)According to the principle of voluntariness,47 subjects with LCS were selected to sign the informed consent.They were randomly divided into the experimental group and the control group,including 24 subjects in the experimental group,6 men and 18 women;23 subjects in the control group.The experimental group received 8 weeks of exercise intervention,and the control group exercise was performed by themselves.Before the treatment,the patients were assessed for disease relevance(including basic data,pain classification index,APT,spinal function status,dysmenorrhea history,etc.).In the course of the study,23 subjects were dropped,including 12 subjects in the experimental group and 11 subjects in the control group.Finally,24 subjects were included,12 subjects in the experimental group and 12 subjects in the control group.Before and after treatment,the pain scores(Low Back Pain(LBP),Dysmenorrhea,Mc Gill Pain Questionnaire,VAS),APT,spinal function(various vertebral body angles,TS,LS,Sacs/Hip J.)were recorded.The results are as follows: the angle of inclination line,the length of back from Th1 to S3,the overall curvature of T1-S1,the overall curvature and activity of L1-S1,and the photos of patients’ posture evaluation.3.Study on the muscle activation sequence before and after exercise intervention in Lower Crossed Syndrome(Experiment 3)Delsys surface electromyography was used to test the difference of muscle activation sequence between the control group(n=12)and the experimental group(n=12)before and after intervention.Results: 1.A survey of the influence of routine physical exercise on Lower Crossed Syndrome(Experiment 1)1)Investigation of APT of sedentary people: PE(20.97 ±3.55),NON-PE(20.46 ± 2.08)2)Results of spinal function test: In Matthias test 1,and there was significant difference in LS(P<0.05),and there was no significant difference in other parameters(P>0.05).2.An empirical study on exercise intervention of Lower Crossed Syndrome(Experiment 2)1)Comparison of Mc Gill Pain Questionnaire before and after and between groups: The pain index of VAS and PPI in the experimental group and compare with control group after study,and between the two groups was significant difference(P<0.05).2)Comparison of APT parameters before and after and between groups: The experimental group before and after study and compare these two groups after study,and also the control group before and after the test was significant difference.(P<0.001).3)Results before and after spinal function test and between groups: i.In standing posture: There were significant differences in Sac/Hip J.,LS and total back length in the experimental group and LS between the two groups,and the other indexes were no significant difference(P<0.05).ii.In sitting posture: In T2/3,Incl.and Th5/6 in the control group,and also in L2/3,L4/5 and Sac/Hip J.between the two groups were significant differences(P<0.05),and the other indexes were no significant difference(P>0.05).iii.Matthiass test: In Th8/9,L1-S1,Sac/Hip J.,LS and Incl.in the experimental group after exercise intervention and L2/3 between the two groups after the experiment,and in L3/4 and L5/S1,Incl.and LS in the experimental group before and after were significant differences in test 1,and in the control group,there were significant difference in Th6/7,Incl.and the whole back length before and after intervention in test 2(P<0.05),and there was no statistical significance in the other indexes before and after exercise intervention.3.Research results of muscle activation sequence before and after exercise intervention in Lower Crossed Syndrome(Experiment 3):1)The order of muscle activation in the experimental group before and after intervention:(1)The activation sequence of extensor muscles in prone position: a)Before the study(R): 1 Hamstring(R),2 Erector Spinae(ES)(L),3 ES(R).b)After the study(R): 1 Hamstring(R),2 ES(L).c)Before the study(L): 1 Hamstring(L),2 ES(L),3 ES(R).d)After the study(L):1 Hamstring(L),2 ES(L),3 ES(R).(2)The activation sequence of lateral abductor muscles: a)Before the study(R): simultaneous activation of Tensor Fascia Lata(TFL)(R)and Musculus Gluteus Medius(MGM)(R).b)After the study(R): 1 MGM(R),2 TFL(R).c)Before the study(L):1 TFL(L),GM(L)and Lumbar Quadrate Muscle(LQM)(L)were activated simultaneously.d)After the study(L):1 TFL(L),2 MGM(L).2)The order of muscle activation in the control group before and after intervention:(1)The activation sequence of extensor muscles in prone position: a)Before the study(R): 1 Hamstring(R),2 ES(L),3 ES(R).b)After the study(R): 1 Hamstring(R),2 ES(R),3 ES(L).c)Before the study(L): 1 Gluteus Maximus(GM)(L),2 Hamstrings(L)and ES(R),3 ES(L).d)After the study(L): 1 ES(R),2 Hamstring(L),3 ES(L).(2)The activation sequence of lateral abductor muscles: a)Before the study(R): the TFL(R),MGM(R)and LQM(R)were activated simultaneously.b)After the study(R):(R): 1 TFL(R),2 MGM(R),3 LQM(R).e)Before the study(L): simultaneous activation of TFL(L)and MGM(L).f)After the study(L): 1 MGM(L),2 TFL(L).i.Conclusion: Regular physical exercise has no good effect on body posture,long-term systematic and targeted exercise intervention can promote the adjustment of body posture,functional recovery,low back pain and dysmenorrhea relief.Moreover,the recovery of pelvic rotation was earlier than that of APT,and the pain relief was earlier than that of posture,and the functional recovery was slower than that of posture adjustment.
